Load from Amazon AWS S3 file.
Initialize with bucket and key name.
Parameters
bucket – The name of the S3 bucket.
key – The key of the S3 object.
region_name – The name of the region associated with the client.
A client is associated with a single region.
api_version – The API version to use. By default, botocore will
use the latest API version when creating a client. You only need
to specify this parameter if you want to use a previous API version
of the client.
use_ssl – Whether or not to use SSL. By default, SSL is used.
Note that not all services support non-ssl connections.
verify – Whether or not to verify SSL certificates.
By default SSL certificates are verified. You can provide the
following values:
False - do not validate SSL certificates. SSL will still be
used (unless use_ssl is False), but SSL certificates
will not be verified.
path/to/cert/bundle.pem - A filename of the CA cert bundle to
uses. You can specify this argument if you want to use a
different CA cert bundle than the one used by botocore.
endpoint_url – The complete URL to use for the constructed | https://api.python.langchain.com/en/latest/document_loaders/langchain.document_loaders.s3_file.S3FileLoader.html |
5f2a214d5ae3-1 | endpoint_url – The complete URL to use for the constructed
client. Normally, botocore will automatically construct the
appropriate URL to use when communicating with a service. You can
specify a complete URL (including the “http/https” scheme) to
override this behavior. If this value is provided, then
use_ssl is ignored.
aws_access_key_id – The access key to use when creating
the client. This is entirely optional, and if not provided,
the credentials configured for the session will automatically
be used. You only need to provide this argument if you want
to override the credentials used for this specific client.
aws_secret_access_key – The secret key to use when creating
the client. Same semantics as aws_access_key_id above.
aws_session_token – The session token to use when creating
the client. Same semantics as aws_access_key_id above.
boto_config (botocore.client.Config) – Advanced boto3 client configuration options. If a value
is specified in the client config, its value will take precedence
over environment variables and configuration values, but not over
a value passed explicitly to the method. If a default config
object is set on the session, the config object used when creating
the client will be the result of calling merge() on the
default config with the config provided to this call.

aws_access_key_id – The access key to use when creating
the client. This is entirely optional, and if not provided,
the credentials configured for the session will automatically
be used. You only need to provide this argument if you want
to override the credentials used for this specific client.
aws_secret_access_key – The secret key to use when creating
the client. Same semantics as aws_access_key_id above.
aws_session_token – The session token to use when creating
the client. Same semantics as aws_access_key_id above.
boto_config (botocore.client.Config) – Advanced boto3 client configuration options. If a value
is specified in the client config, its value will take precedence
over environment variables and configuration values, but not over
a value passed explicitly to the method. If a default config
object is set on the session, the config object used when creating
the client will be the result of calling merge() on the
default config with the config provided to this call.

of the client.
use_ssl – Whether to use SSL. By default, SSL is used.
Note that not all services support non-ssl connections.
verify – Whether to verify SSL certificates.
By default SSL certificates are verified. You can provide the
following values:
False - do not validate SSL certificates. SSL will still be
used (unless use_ssl is False), but SSL certificates
will not be verified.
path/to/cert/bundle.pem - A filename of the CA cert bundle to

override this behavior. If this value is provided, then
use_ssl is ignored.
aws_access_key_id – The access key to use when creating

75f03c9aded1-0 | langchain.document_loaders.unstructured.UnstructuredFileLoader¶
class langchain.document_loaders.unstructured.UnstructuredFileLoader(file_path: Union[str, List[str]], mode: str = 'single', **unstructured_kwargs: Any)[source]¶
Load files using Unstructured.
The file loader uses the
unstructured partition function and will automatically detect the file
type. You can run the loader in one of two modes: “single” and “elements”.
If you use “single” mode, the document will be returned as a single
langchain Document object. If you use “elements” mode, the unstructured
library will split the document into elements such as Title and NarrativeText.
You can pass in additional unstructured kwargs after mode to apply
different unstructured settings.
Examples
from langchain.document_loaders import UnstructuredFileLoader
loader = UnstructuredFileLoader(“example.pdf”, mode=”elements”, strategy=”fast”,
)
docs = loader.load()

class langchain.document_loaders.parsers.docai.DocAIParser(*, client: Optional[DocumentProcessorServiceClient] = None, location: Optional[str] = None, gcs_output_path: Optional[str] = None, processor_name: Optional[str] = None)[source]¶
Initializes the parser.
Parameters
client – a DocumentProcessorServiceClient to use
location – a GCP location where a DOcAI parser is located
gcs_output_path – a path on GCS to store parsing results
processor_name – name of a processor
You should provide either a client or location (and then a clientwould be instantiated).

get_results(operations)
is_running(operations)
lazy_parse(blob)
Parses a blob lazily.
operations_from_names(operation_names)
Initializes Long-Running Operations from their names.
parse(blob)
Eagerly parse the blob into a document or documents.
parse_from_results(results)
__init__(*, client: Optional[DocumentProcessorServiceClient] = None, location: Optional[str] = None, gcs_output_path: Optional[str] = None, processor_name: Optional[str] = None)[source]¶
Initializes the parser.
Parameters
client – a DocumentProcessorServiceClient to use
location – a GCP location where a DOcAI parser is located
gcs_output_path – a path on GCS to store parsing results
processor_name – name of a processor | https://api.python.langchain.com/en/latest/document_loaders/langchain.document_loaders.parsers.docai.DocAIParser.html |

batch_parse(blobs: Sequence[Blob], gcs_output_path: Optional[str] = None, timeout_sec: int = 3600, check_in_interval_sec: int = 60) → Iterator[Document][source]¶
Parses a list of blobs lazily.
Parameters
blobs – a list of blobs to parse
gcs_output_path – a path on GCS to store parsing results
timeout_sec – a timeout to wait for DocAI to complete, in seconds
check_in_interval_sec – an interval to wait until next check
whether parsing operations have been completed, in seconds
This is a long-running operations! A recommended way is to decoupleparsing from creating Langchain Documents:
>>> operations = parser.docai_parse(blobs, gcs_path)
>>> parser.is_running(operations)
You can get operations names and save them:
>>> names = [op.operation.name for op in operations]
And when all operations are finished, you can use their results:
>>> operations = parser.operations_from_names(operation_names)
>>> results = parser.get_results(operations)
>>> docs = parser.parse_from_results(results)
docai_parse(blobs: Sequence[Blob], *, gcs_output_path: Optional[str] = None, batch_size: int = 4000, enable_native_pdf_parsing: bool = True) → List[Operation][source]¶
Runs Google DocAI PDF parser on a list of blobs.
Parameters
blobs – a list of blobs to be parsed
gcs_output_path – a path (folder) on GCS to store results
batch_size – amount of documents per batch
enable_native_pdf_parsing – a config option for the parser | https://api.python.langchain.com/en/latest/document_loaders/langchain.document_loaders.parsers.docai.DocAIParser.html |
5a9be0d1541a-2 | enable_native_pdf_parsing – a config option for the parser
DocAI has a limit on the amount of documents per batch, that’s why split abatch into mini-batches. Parsing is an async long-running operation
on Google Cloud and results are stored in a output GCS bucket.

This is a convenience method for interactive development environment.
Production applications should favor the lazy_parse method instead.
Subclasses should generally not over-ride this parse method.
Parameters
